Email Issue - Failed Login

I just got a new VPS server and have updated CPANEL to its latest release but for the last 2 days at around 9pm all my emails experience the same issue: FAILED LOGIN

If I go through outlook a popup comes up to check the password which is correct. If I go through webmail and I use Roundcube, I get the FAILED LOGIN message coming up.

I have also noticed that when then issue happens all my FORWARDERS get deleted.

This is what my hosting company did to resolve the issue:
"I have updated the account again and this time have made changes to the hostname and DNS entries. Hopefully this will be enough to prevent this from happening again."

It fixed it temporarily and the same issue happened the night after. Is there another option?

I would have to find out regarding what changes were made as I created a ticket and the quote I posted earlier was their reply to me. The hostname they set as centreholidays.com and yes it is VPS OpenVZ

The hostname cannot be a domain on the machine but must be a subdomain on a domain on the machine. If you are using centreholidays.com instead of something like server.centreholidays.com, then centreholidays.com will be owned by the user nobody and won't be able to properly work for email.

Can you please try running this command:

Code:

/scripts/whoowns centreholidays.com

If the domain having the issues is centreholidays.com then having it as the hostname is causing an issue.

These look fine then. Could you find out from your VPS provider exactly what changes they made? Also, you could open up a ticket with us at WHM > Support Center > Contact cPanel or using the link I have in my signature for us to see if we can determine what is going on for these issues with login and the forwarders being removed.
